Model wastewater whose composition resembled that of pulp and paper wastewater was treated by electrocoagulation under laboratory conditions. The process was carried out in an electrolytic tank with aluminum electrodes. Following electrocoagulation, sedimentation and decantation, COD, turbidity, suspended solids and color were determined in a solution above the sludge layer. The parameters of COD...
Zearalenone is a mycotoxin widely occurring in cereals and animal feed, and it is associated with hyperestrogenism and other reprodutive disorders in animals. A new method of detoxication of feed- stuffs involves alkaline hydrolysis of toxic macrolactone (1) (as well as model compounds (2a, 2b)). The method caused modification of zearalenone structure under mild conditions and the toxin underwent...
Zearalenone (ZEA) is a member of macrocyclic lactons family. It is a toxin - phytosteride produced by fungi of Fusarium ssp. genus. Zearalenone contaminates food and animal feeding stuffs and its destruction is difficult. It requires application of particular compounds that would bind zearalenone in the feed or feeding stuff or in the gastrointestinal tract and decrease its bio-accessibility. It should...
The processes of exchange and sorption of orthophosphoric acid on Amberlite IRA-402 were studied. The concentrations of phosphate phosphorus and hydrogen ions were determined in initial and equilibrium solutions. It was found that there is a linear dependence between the amounts of phosphorus exchanged and/or sorbed in the model system tested (Amberlite) and the quantity and concentration of H3PO4...
